HUTCH-VALVE-OPERATING MECHANISM.

Specification of Letters Patent.

Patented Oct. 25, 1921.

Application filed March 8,1919. Serial No. 281,418.

To all whom it may concern.

Be it known that we, AXEL G. J. RAPP and LAURENCE M. EwELL, citizens ofthe United States, residing, respectively, at Chicago, in the county ofCook and State of Illinois, and at East Liberty, Pittsburgh, 1n thecounty of Allegheny and State of Pennsylvania, have invented a certainnew and useful Improvement in Hutch-Valve-Operating Mechanism, of whichthe following is a specification.

Our invention relates to a hutch-valve operating mechanism for use inconcentrating jigs and the like, and has for one object to provide anautomatically operated and timed mechanism for periodically opening andclosing the valve in the bottom of the hutch, so as to provide for theescape of sludge while preventing any unnecessary loss of water.

It is illustrated more or less diagrammatically in the accompanyingdrawings wherein- Figure 1 is an end elevation of a jig partly insection with the valve mechanism installed;

Fig. 2 is a plan view of the valve operating mechanism;

Fig. 3 is a detailed section along the lines 3-3 of Fig. 2.

Fig. 4 is a detail section along the lines 4=4 of Fig. 2.

Like parts are indicated by like characters in all the figures.

A is a jig having at its bottom a valve A carried on the valve rod Awhich has near its upper end the lifter stop, A and at its top thehandle A.

B is a valve lifter arm rotatably mounted on rocker shaft D and havingat its upper end the portion B provided With the bearing surface B andat its other end the portion B carrying in its end the bearing B*.

C is a lifting dog slotted at C to admit the portion B of the lifter armB upon which it is mounted, and provided with the hooked portion C andthe upper extension C which has on its under side the bearingsurface orbuffer C D is a rocker shaft upon which is keyed the arm D It has keyedto it the levers D which have rotatably mounted between them at theirends the pawl D D is a ratchet wheel rotatably mounted on the rockershaft D, notched as at D and having one substantially deeper notch D.

E is a shaft upon which is mounted a gear wheel E and the crank E to thepin E of which is connected one end of the connecting rod E5 The otherend of this connecting rod is connected to the rocker arm D F is a shaftcarrying at its end the pinion F which is in mesh with the gear Wheel EThe shaft F has mounted upon it the sprocket wheel F in mesh with thedriving chain F which is driven by sprocket wheel G mounted on drivingshaft G.

H 18 a tripper rod secured to the frame of the jig, bent at its upperend to form the hook H having at its lower point the operating surface Hadapted to strike against and depress the upper projection C of thelifting dog 0 I I is a ratchet dog supported at I on the hutch base andhaving the flattened end I adapted to ride upon and engage the teeth ofthe ratchet D.

J is a counter weight adapted to fit upon and slide along the shortportion I of the ratchet dog I,

The use and operation of our invention are as follows:

By means of suitable gearing a rocking motion is imparted to the rockershaft D upon which are mounted two lever arms D These levers havebetween them a ratchet wheel D and the valve lifting arm B, and carry attheir ends a pawl D As the rocker arms are rocked down, the pawl engagesone of the notches in the ratchet, rotating the ratchet wheel. As theyare rocked up, the pawl rides over these notches. Once in everyrevolution of the ratchet wheel the pawl will enter the deep notch. Vhenit does so it penetrates sufficiently within the ratchet wheel to engagethe end B of the valve lifter arm, depressing it and raising its otherend thereby raising the lifting dog C which engages the lifter stop onthe valve rod A and thus raises the rod. \Vhen the rod has been raisedsufiiciently the upper projection of the lifting dog strikes the tripperrod, and is depressed and pushed out of engagement with the lifter stop,so that the valve rod is dropped, and the valve is thereby closed.

If more than one deep notch is used, and a plurality may be desirable togive a more frequent action of the valve, then each time that a deepnotch is engaged by the lever,

the valve will be opened.

We claim 1. In a valve operating mechanism, the combination of a drivingpart, a power transmitting part, means for intermittently connectingthem, a valve, a connection between it and said power transmitting part,and means for terminating said connection after a predetermined travelof said valve.

2. In a valve operating mechanism, the combination of a driving part, apower transmitting part, means for intermittently connecting them, avalve, a connection between it and said power transmitting part,comprising a dog adapted to engage said valve, and means for terminatingsaid connection after a predetermined travel of said valve, comprising adog tripping element.

3. In a valve operating mechanism for hutches and the like, thecombination of a driving part, a power transmitting part, means forintermittently connecting them, a lifting valve, and means forintermittently connecting the power transmitting part with the valve.

4. In a valve operating mechanism for hutches and the like, thecombmation of a driving part, a power transmitting part,

'means for intermittentl connectin them a y a: a

lifting valve, means for intermittently connecting the powertransmitting part with the valve and means for intermittently disengaginthem.

5. n a valve operating mechanism for hutches and the like, thecombination of a driving part, a power transmitting part, means forconnecting them, comprising a ratchet wheel and pawl, a lifting valveand means for intermittently connecting the power transmitting part withit.

6. In a valve operating mechanism for hutches and the like, thecombination of a driving part, a power transmitting part, means forconnecting them, comprising a ratchet wheel and pawl, a lifting valveand means for intermittently connecting the power transmitting part withit and means for intermittently disengaging the power transmitting partfrom it. I

7. In a valve operating mechanism for hutches and the like, thecombination of a driving part, a power transmitting part, means forintermittently connecting them, comprising a ratchet wheel with one ormore notches substantially deeper than the others and a pawl, a liftingvalve and means for connecting the transmitting part to the valve whenthe notches.

8. In a valve operating mechanism for hutches and the like, thecombination of a driving part, a power transmitting part, means forconnecting them, comprising a ratchet wheel withone or more notchessubstantially deeper than the others and a pawl, a lifting valve andmeans for intermittently connecting the power transmitting part with itadapted to be engaged by the pawl when it penetrates said deep notches.

9. In a valve operating mechanism for hutches and the like, thecombination of a driving part, a power transmitting part, means forintermittently connecting them, a lifting valve and means for connectingthe power transmitting part with the valve, comprising a lifter dog andstop.

10. In a valve operating mechanism for hutches and the like, thecombination of a driving part, a power transmitting part, means forconnecting them, a lifting valve and means for intermittently connectingthe power transmitting part with it, comprising a lifter dog and stop,and means for intermittently disengaging the power transmitting partfrom it.
